sexy eyes The Connection Between Mydriasis & Sexual Arousal

Mydriasis is a condition in which the pupil of the eye is dilated for unusually long and does not return to the normal state for a noticeable period. There could be a number of causes to that, the most frequents ones of which include the use of certain drugs and trauma to the eye. However, you would be interested to know that mydriasis is even caused in some cases due to very strong sexual arousal and the excitement associated to the emotion.

In a study carried out by the researchers from the New York Medical College, the New York University School of Medicine and a few other medical institutes based in New York City, it was found that orgasms potentially trigger angle-closure, which is a condition involving damage to the optic nerve. At least, it is found that sexual arousal can lead to the enlargement of the pupil of the eye.

In a case, orgasm was even found to have caused papillary block along with angle closure, but with a preexisting condition of narrow chamber angle. It is explained by the fact that the papillary block and the condition of mydriasis is caused by the stimulation of the sympathetic and parasympathetic nervous systems, which in turn stimulate the iris sphincter, which helps making the movement of the pupil.

In this case, the stimulation of the sympathetic and parasympathetic systems gave rise to dilated pupils due to dark and also because of the zonular relaxation caused by the ciliary contraction giving rise to the damage to the nerve and the condition of mydriasis. Oxytocin, a hormone associated with orgasm and the reproductive system, is also a factor behind the instances of mild and moderate mydriasis during sexual arousal and orgasm.

Mydriasis – What Are the Risks and Complications?

mydriasis dilated pupils Mydriasis What Are the Risks and Complications?

Mydriasis is certainly a disorder, but it is not really a serious threat to the eye, apart from any other injury which would have caused the condition in the first place. In most cases, the condition of mydriasis subsides by itself. Therefore, there are not really any major risks and complications associated with the condition.

However, a lot of people who do experience the condition staying for a very long time, do seek some sort of treatment and drugs to get the condition of the pupil back to normal. Most of the time, no medicine is really required for the treatment and neither do most eye specialists or other related physicians recommend the use of any medicine, but in some cases a few medicines could be prescribed.

Usually it is safer to avoid using any medicine which will have adverse side effects, which could aggravate the weakness in the eye or could lead to some other possible condition. Usually, the physicians recommend the patient to wait for the recovery of the damage to the parasympathetic nerve that caused the problem.

In the meanwhile, the victims suffering from mydriasis may complain of sensitivity to light. In such a case, either opaque-colored contact lenses or light-sensitive sun glasses should be used to avoid discomfort or any other adverse reaction to the eye.

Some people usually fear other symptoms, which have been preexisting or resulted coincidentally at the same time of the occurrence of the condition, such as headaches, but there really is not any connection, unless the symptoms pertain to the damage of the optic nerve. But in that case too, it has nothing to do with Mydriasis itself.
